• Tracking versions with PAV

  The PAV ontology specializes the W3C PROV-O standard to give a lightweight approach to recording details about a resource, giving its Provenance, Authorship and Versioning. Our paper on PAV explores all of these aspects in details. In this blog post we discuss Versioning as modelled by PAV, including their hierarchical organization.

  • Version numbers {#versionnumbers}
    • Semantic versioning {#semver}
  • Making versions retrievable {#retrievable}
  • Ordering previous versions {#ordering}
    • Providing provenance for each version {#each-version}
  • Related work {#relatedwork}
    • PROV-O revisions {#provo}
    • Qualified revisions {#qualified}
    • DC Terms {#dcterms}
    • schema.org {#schemaorg}
  • Organize the versions {#organize}
    • Earlier versions {#earlier}
    • Has a version (snapshots) {#hasVersion}
    • Current version {#current}
    • Hierarchies all the way down {#hierarchies}

  Versioning is commonly used for software releases (e.g. Windows 8.1, Firefox 26, Python 3.3.2), but increasingly also for datasets and documents. For the purpose of provenance, a version number allows the declaration of the current state of a resource, which can be cross-checked against release notes and used for references, for instance to indicate which particular version of a dataset was used in producing an analysis report.
